This process is optional and purely depends as per customer's requirement.
Color Anodizing is a post Anodising electrolytic process in which the anodised load is transferred and immersed to a tank containing a tin solution.
A color code number is entered into a computer, which calculates the emersion time required to produce the desired color match. An alternating current is passed to the item whilst immersed.

Coloring Techniques:
Color Anodizing: After Anodizing components can be colored in following ways.
Organic dyestuffs Coloring: Organic dye pigments can be used to color freshly anodized components. The components that undergo this process are usually not exposed to ultra violet radiations as the chances of color fading is more. yes, have different degrees of fastness, and for any given dye the deeper the shade, the faster the color. Where fastness to light is important, dyes that have high fastness index should be used.
Inorganic Pigments Coloring: Many of the general operating recommendations given for Organic dyes also apply to inorganic Pigments. Very limited colours can be obtained and the produced colours are more stable to light and heat when compared to organic colours.
